automation

worst case scenario: 

automation leads to permanent mass unemployment everywhere 

but housing, food, energy and transport becomes very cheap 

because of automation 

so companies earns a lot of money from automation 

so governments earns a lot of tax money from automation 

and governments only have low costs because of automation 

so governments can afford to pay welfare to all unemployed 

and all unemployed can afford to buy everything they need to survive 

because housing, food, energy and transport becomes is very cheap 

so companies earn money 

and governments earn more money than they spend 

and unemployed get more welfare than they spend 

so unemployed invest their money 

by buying stocks in publicly traded companies 

and by buying stocks in private companies 

and by starting their own companies 

normal scenario: 

automation doesn't change unemployment percentages 

and housing, food, energy and transport becomes very cheap 

because of automation 

so companies earns a lot of money from automation 

so governments earns a lot of tax money from automation 

and governments only have low costs because of automation 

so governments can afford to pay welfare to all unemployed 

and all unemployed can afford to buy everything they need to survive 

because housing, food, energy and transport becomes is very cheap 

so companies earn a lot of money 

and governments earn more money than they spend 

and unemployed get more welfare than they spend 

so unemployed invest their money 

by buying stocks in publicly traded companies 

and by buying stocks in private companies 

and by starting their own companies 

and people with jobs invest their money 

by buying stocks in publicly traded companies 

and by buying stocks in private companies 

and by starting their own companies 

because automation will make 

housing, food, energy and transport becomes very cheap 

so that no humans will have to worry 

about having enough money to survive 

and that will be revolutionary for humanity
